Memory Foam vs. Latex: What’s the Difference?

Memory foam and latex share similar properties —body-contouring, pressure relief, motion isolation, and little to no noise potential. Both types of mattresses are excellent choices for couples, athletes, and back pain sufferers.

We share details and features that distinguish each type of mattress, including benefits and drawbacks so you can decide which type is the best mattress for you.

What is Memory Foam?

Memory foam, or viscoelastic polyurethane foam, was created by NASA in the 60s and first appeared in mattresses in the early 90s. Memory foam is a polyurethane foam treated with petrochemicals for a denser and more viscous material.

Body weight and heat softens memory foam, causing it to form around the body’s natural curves for pressure point relief. Once weight is removed, memory foam goes back to its original shape.

Memory foam is naturally hypoallergenic, preventing dust mites and other allergens from invading the mattress and irritating allergies.

Structure

A typical memory foam mattress contains a comfort layer of memory foam and a support layer of high-density foam. Memory foam mattresses weigh between 80 pounds to 100 pounds for a queen size.

Lifespan

Memory foam beds last between 7 to 9 years.

Average Cost

The average cost of a queen size memory foam mattress is $1044.

Pros

• Contouring close to the body for pressure relief
• Motion isolation
• Sleeps silently
• Hypoallergenic

Cons

• Risk of overheating
• Off-gassing odor
• Feeling “stuck”

Types of Memory Foam

Traditional memory foam has a high risk of overheating because of its dense structure and lack of airflow. To combat this, mattress manufacturers incorporate cooling features like gel, copper, and graphite in their memory foams. Some memory foam mattress brands also choose to use plant-based memory foam which is more porous and breathable.

Gel Memory Foam

Gel memory foam contains either liquid gel or gel beads, that have been mixed in or swirled into traditional memory foam during the manufacturing process. Cooling gels absorb and disperse body heat to regulate temperature.

Plant-based

During the manufacturing process, plant-based oils partially replace petroleum to produce a breathable, more responsive memory foam. This type of memory foam has little to no VOC (volatile organic compound) emissions.

Open-cell

Injecting large amounts of air into memory foam creates an open cell structure with more air pockets, allowing better air circulation inside the mattress.

Copper and Graphite Infusions

Copper and graphite are natural conductors of heat. Copper-infused memory foam pulls heat away from the body and may improve local blood flow.

Graphite is normally used to cool down high-powered machines, like PCs. Graphite-infused memory foam draws heat away from the body.

The Zoma Mattress has quite a few features that set it apart from the typical run-of-the-mill memory foam mattress or other gel memory foam beds. With its responsive, durable foams and cooling features, the Zoma Mattress is designed to help you sleep longer for better rest and recovery.

The top layer of gel memory foam features Triangulex™ technology, with triangular cutouts placed in the head, shoulder, and leg sections. By covering roughly two-thirds of the mattress, these cutouts increase pressure relief to sensitive areas while allowing the middle of the bed to focus on back support.

The mattress’s transition layer is named Reactiv™ for its responsiveness, making it easy for sleepers lie down without sinking too far and move across the surface when they want to get out of bed. At the base of the mattress is Support+ foam, engineered to increase the bed’s overall durability.

The Zoma Mattress comes with a 100-night sleep trial and a 10-year warranty.

What is Latex?

Latex was first introduced in mattresses in 1931. Similar to memory foam, latex conforms to the body to relieve pressure points, restricts motion transfer, and sleeps silently. The difference is latex sleeps cooler and has a responsive bounce. There are two types of latex —synthetic and natural.

Synthetic latex foam is created through a chemical process, using petrochemicals to mimic the properties of a natural latex mattress, except it’s less durable with higher off-gassing potential.

Natural latex is made from rubber tree sap. Two forms of natural latex are Dunlop and Talalay. Dunlop latex contains 100% natural latex and is denser and more durable than Talalay. During the Talalay process, polyurethane fillers are added to natural latex foam to create its signature soft, sponge-like feel.

Both types of latex are hypoallergenic, so sleepers won’t have to worry about dust mites and allergens getting into the mattress. However, organic latex mattresses are the most durable, potentially lasting decades.

Structure

A latex bed contains a comfort layer of latex and a support layer of high-density foam or latex. Latex mattresses weigh between 100 pounds to 170 pounds for a queen-size.

Lifespan

The average lifespan of a latex mattress is between 8 to 9 years.

Average Cost

The average cost of a queen size latex mattress is $1970.

Pros

• Rounded contouring around the body to relieve pressure
• Motion isolation
• Sleeps silently
• Cooler
• Responsive bounce
• Hypoallergenic

Cons

• Risk of overheating (stronger in synthetic latex)
• Off-gassing odor potential (stronger in synthetic latex)
• Higher price tag
• Heavier than other mattress types

FAQs

Do memory foam mattresses have latex?

Memory foam mattresses usually contain foam layers —they might contain a transitional layer of latex, depending on the brand.

Is latex or memory foam better for back pain?

Some of the best mattresses for back pain are memory foam. Memory foam reduces more pressure points, provides enhanced support to the lower back, and is less expensive than latex. Try one with a medium-firm feel.

Why is latex so expensive?

Latex is an organic material sourced from rubber trees, so it’s a bit more expensive than other materials. However, latex is supremely durable and long-lasting, so people often find an organic latex mattress worth the investment.

What’s safer, memory foam or latex?

All-natural, organic latex mattresses are technically safer than memory foam because they contain less chemicals and are made from renewable resources. However, memory foam mattresses are also completely safe for sleepers. If you’re concerned about off-gassing, look for memory foam mattresses with a CertiPUR-US® certification.

Can bed bugs live in foam mattresses?

It’s harder for bed bugs to penetrate foam mattresses, like latex and memory foam beds, but they still can find a way inside of your mattress. Plus, if they can’t make their way inside your mattress, they’ll still loom around your bedframe and bedroom.

What’s Your Preference?

Now that you know the similarities and differences between memory foam and latex, it’s time to decide which mattress you prefer. A new mattress could be just what you need for better comfort and support for a good night’s sleep.
